Akira was a well built and attractive boy in his late teens, he had a muscular body, brown eyes and messy brown hair. His preferred clothing seems to be a yellow shirt with red outlines and an A on the left chest area, and a pair of blue jeans.

He is seen exploring the Himalayas along with his Father Professor Fudo when the two fall through a crack in the ice. They are then confronted by four demons Rerasu, Daruni, Zennon and Devilman. They are both killed and Zennon tells the others to fight it out for control over Akira's body. Devilman wins and uses Akira's body convincing many people its really him throughout the series.
